"A tweet came through recently that Teslas in Japan will have a CHAdeMO adapter included.http://bit.ly/RLzgRW"

Does this mean that on a North American CHAdeMO station we could theoretically purchase and use the same adapter the Japanese will receive? If so, that is great news. I would definitely be interested. :-)

I don't have a copy of the CHAdeMO spec, but the CHAdeMO organization is looking forward to an increase to 200A:
In the future, as the price of the power units continues to decrease and the performance of the battery continues to improve, faster and higher power chargers be eventually necessary. In fact, the geometry of CHAdeMO connector is designed to allow for 200A, which means it can almost double its power level.http://www.chademo.com/technology/optimal/

I don't have it too, that's why I gave you link to wiki :)

The problem is; having to rely 100% on TC being installed, when travelling in Europe. Driving past Chademo chargers on a roadtrip, would be a real bummer!! Chademo is compatible to 5 or 6 different EV brands, but not Tesla ... Why deviate or seperate from the rest of the EV market? Why not join the rest and provide the TC as a bonus for Tesla owners!!! The Model S & X would be superior to the competition anyway. I suppose the ultimate question is this: WHEN can i take my Model S from Norway to south of France and not having to spend overnights every 480 km? Is it viable? Will they be installed along the german autobahn or country road reststops? However, there are rumors on the web that Chademo might be compatible to Tesla in Japan. It is a true dissapiontment if there is no adaptor to the existing EV infrastructure, regardsless of how amazing the Model S is. I understand that the advantage of the TC is great for Tesla owners, but having to follow the TC roadmap on every trip you take ??

Dude, they ARE working on an adapter. It's just not ready yet.

What is the charge voltage for the S85?
If it is 500v then you should be able to charge at 62.5kW right now.
However, I seem to remember that it was 375v (someone please verify). If so then it would be only capable of charging at 46.8kW. Still over half as fast as the supercharger for a half charge and even better than that for a full charge because the supercharger slows down the charge rate when it gets fuller.
If these were CHAdeMO chargers become ubiquitous ie. in hotels and malls everywhere (as is already the case I believe in Japan), along with the Tesla supercharger network, it would make EV travel as easy as it is with and ICE (IMO)

lph:
The supercharger does not slow down near full. The car battery management slows the charge to protect the battery regardless the source or amount of available electricity. When (if) there is a CHAdeMO charger regardless of it's charge rate it will also slow down.

Ghillair:
True, but the CHAdeMO will be charging at its full rate for longer because its max rate is lower.

Did you hear in US about the new Universal connector, that the EU forces now?

@Vawlkus
I know, i said "if".. Its nice to be sure when spending 110K USD on a car. Disappointment hasn't struck me yet... ;) Our plan for two household cars; 1 Tesla Model S and 1 hybrid hatch. Thinking it would be nice to take the Model S for a long trip, using the public EV grid map to locate charge points.

silly comment. It starts slower and stays slower.

It does not matter if it is not as fast as a Supercharger. If an extra CHAdeMO-adapter would mean that the consumer has more charging options to choose from, then that is a positive step forward for all Tesla EV owners. As charging at more locations is possible. And that is very convenient for the consumer.

Tesla seems to have bet on the SAE standard rather than CHAdeMO. Look at the 4 pin charging outlet 2x power 2x comms. I bet the comms pins use the power line protocol that SAE uses. Tesla saved 2 beefy power pins over SAE by supporting both AC & DC over the plug pins.

The CHAdeMO plug has EIGHT control pins and 2 power pins. The comms is a combination of digital and analog control. Very complicated. Everybody imagines the adapter to be a little cylinder like the J1778 for around $50.

Would you buy the CHAdeMO adapter if it looked more like the mobile charging cable (a big control box on a thick cable) and cost several hundred dollars? In Japan a Model S owner might opt for the CHAdeMO cable instead of the mobile cable.

@ir| FEBRUARY 16, 2013: Tesla seems to have bet on the SAE standard rather than CHAdeMO.

I noticed a new charging station at Picacho Peak AZ, that is a dual CHAdeMO/SEA Combo plug by GoE3. Here is a picture from the grand opening:

Ecotality also says that their Blink CHAdeMO chargers can be converted to dual plug.

8 data? Somebody needed to lecture those birds on the benefits of KISS.

Thing is that adapter may not be compatible with the American charger; the upgrades to the European charger might mean its gonna take an upgrade to the existing chargers to make it work.

Pure speculation Vawlkus. It is technically possible without changes, so let's not reach conclusions without evidence.

Vawlkus |

It is indeed pure speculation, but based on the tidbits of information we do have, it IS plausible.

All we know is that previously it was stated that the charger was unlikely to get a chademo adapter, then we hear that Japan MIGHT get one of those adapters, and then finally we hear that the three phase adapter for Europe would be chademo capable. To me, that says that the current charger isn't yet able to adapt to the chademo chargers, but it may be possible to engineer an adapter, or failing that, engineer an upgraded charger to replace the current charger in American cars. That's all IMHO of course, until we get more info from Tesla.

I don't think it really matters what charger is in the car. CHAdeMo is a DC charging system. Basically like a lower powered version of the Telsa Supercharger where the connection is direct to the battery. So as long as the adapter can make the car think it's a supercharger, it should work. Assuming Tesla uses the same cable connection at the car and they don't block the it via software, there's no reason an adapter from another country won't work. Regardless, I'm still keeping my fingers crossed they just release one for the US and make things easier for us!

"Assuming Tesla uses the same cable connection at the car"

The european spec cars will have a different cable connection at the car. This was confirmed at almost the same time in they confirmed the CHAdeMo connector. European cars will have a Mennekes connector.

Any news on a CHAdeMO adapter yet? Plugshare is showing more and more Blink quickchargers which have CHAdeMO plugs.

J1772 standard allows for 80 Amp output (if memory serves) and in my mind that is what should be deployed ..., "if" deploying J1772.

J1772 is still having "chicken & egg" problems. 80A wiring needs more than 2x the copper of 30A wiring, so cost is an issue. Even though Model S was the sales leader for 2013Q1, Volt and Leaf have higher numbers on the road and even 30A is overkill for them.

I hate that AC Level 2 can be anywhere from 24A to 80A because it is impossible to search for decent chargers. It needs a name AC Level 2.5 to signify anything over 50A.

18 avril 2013

I agree ... or every additional J1772 deployed could simply be 80 Amp capable. I'm thinking we need buy in here!!

@KDF - Huh? Even after translating that makes no sense in this context. What am I missing?

@GeekEV; He's talking about agreements which allow free movement between European countries "Schengen agreements". Probably as answer to few of my messages at the first page of this thread.

@KDF; I don't speak German. I had to translate your message using Google translate.

[rant]
unfortunately my country has some ancient relic and is "bi-lingual" even that this other language (Swedish) is spoken by only 6% of the population, and 99% of those speak Finnish too. We probably have more Russian tourists at any time than we have pure Swedish-talking citizens. For that reason I was forced to learn Swedish and had to drop German because my weekly hours exceeded 45 in school with it. Can't learn everything I guess. There is only 24 hours in a day.

It may be useful to classify full-tank charging opportunities in terms of what the driver does between plugging in and removing the connector.

1. Sleep: In that case, 10kw charging rates will do (240v at 40 amps).
2. Eight hour work day: about the same.
3. Stop and stretch: Takes 90-120kw superchargers.
4. Shop for hours in a mall. Level 3 DC charging.

For mere topping up, less will suffice.

The main problem that I find with road trips is judging sites in terms of what to do in the 6-8 hours without a car.

I hope this adapter comes out soon in the US. It would help me out A Lot!
